here are 85.63 g of CO2 gas in a container maintained at STP. How many liters of CO2 are there in that container?

Iwll give extra points to who gets this for ! what type of reaction is this? ?

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3
